1. A pixel circuit, comprising
a drive module;
a first storage module, wherein the first storage module is connected to a control terminal of the drive module and is configured to store a voltage of the control terminal of the drive module;
a second storage module, wherein the second storage module is configured to store a voltage of a first terminal of the drive module or a voltage of a second terminal of the drive module;
a data write module connected between the control terminal of the drive module and a data line and configured to transmit a data voltage provided by the data line to the control terminal of the drive module in a data write stage;
a first light-emitting control module connected between a first power supply and a first terminal of the drive module and configured to transmit a voltage provided by the first power supply to the first terminal of the drive module after the first light-emitting control module is switched on; and
a light-emitting module connected between a first power supply and a first terminal of the drive module and configured to transmit a voltage provided by the first power supply to the first terminal of the drive module after the first light-emitting control module is switched on; and
an initialization module configured to:
write an initialization voltage to the control terminal of the drive module and the light-emitting module in an initialization stage to initialize the control terminal of the drive module and the light-emitting module, and
continuously write the initialization voltage to the control terminal of the drive module in a compensation stage while the data write module is in an off state.
